A left hand that holds it together

Lesson 63 of 72 · Root, fifth, octave: the bass that carries the song

In this lesson, you will:

1. Learn: The bass player’s job

In a band, the bass almost always plays the root of the chord, on the first beat: it’s what tells your ear “here’s the chord.” When you accompany a singer on your own, your left hand is the bass player.

For a slash chord (C/E), the bass plays the note after the slash. For all the others, it plays just the letter: G → G, Am → A, F♯m → F♯.

Four ways to play a C bass: the root alone, root and fifth, the octave, then 1-5-8.

Watch out: A low bass, yes; low chords, no. At the very bottom of the keyboard, three close notes sound like mush: keep the chords in the middle of the keyboard, and give the left hand single notes, fifths and octaves.

2. Guided play: Fifth and octave

Left hand: first the root and the fifth (little finger, then thumb), then held octaves (5 and 1 together). C – G – Am – F: your arm carries your hand as one block, and the shape doesn’t change.

3. Practice: Bass express

Left hand: little finger (5) on the root, thumb (1) on the fifth or the octave, together. Any octave on this keyboard.

4. Learn: A bass that walks

To link two chords, the bass can walk: on the last beat of the measure, it plays a neighboring note of the next bass note (a whole step or a half step away). This passing note pulls your ear toward the new chord.

Under C – Am – F – G, the bass walks down C, B, A, G, F… then bounces back: A, G, and finally B, which leads straight to C. All these notes fit in a single position: little finger on F, thumb on C.

A dotted half note on the root, then a quarter-note passing note toward the next bass note.

Why this way: You learn bass patterns one at a time, first alone, then under chords: one move at a time, repeated until it becomes automatic. Once your left hand plays “by itself,” your attention is free for the right hand… and for listening to the singer.

5. Guided play: A bass that walks

Left hand alone, without moving your hand: little finger on F, thumb on C. Hold each dotted half note for its full length, then slide to the next bass note.

6. Piece: The 1-5-8 under the chords

The chords of the verse of Let It Be, one per measure: your left hand is what moves the song forward. Left hand: root, fifth, octave, fifth, in quarter notes (fingers 5-2-1-2). The computer plays the chords above.

7. Piece: A bass that walks, hands together

Both hands together: the chords on top, the walking bass underneath. That’s a complete accompaniment! Right hand: the chords in half notes, around middle C. Left hand: the walking bass, without changing position. In the next-to-last measure: F, then G and B to get back to C.
